What's wrong with Tiger Woods' neck?

Question

The World No. 1 quit the Players Championship last week with a neck injury - what exactly is the problem?

Answer 1

Woods withdrew because the pain in his neck was making it to difficult to concentrate on the game, saying on his website: "Playing in pain is not a problem, but when it spasmed, and I couldn't rotate either way, back or forward, I couldn't play." Woods added that: "I might have a bulging disc in my upper back."
